Image processing
capabilities
This section describes the standard capabilities of the scanner.
Refer to the end of this section for information on how to use the
Adaptive Threshold Processor accessory.
Cropping
Cropping is a method of capturing a portion of the total document
being scanned. The host computer provides the scanner with the
following information that defines which portion of the document
is to be captured:
• Left margin — the left-most point is 6 inches (152.4 mm) from
the feeder/transport centerline. The left margin is defined as the
distance from this point.
• Width — the distance from the left margin.
• Top margin — the distance from the leading edge of the
document.
• Length — the distance from the top margin.

of the AX/Y/Z command.
Auto-cropping
This option is only available for Document Scanners with the
Kodak Digital Science
Image Manager accessory installed (not
the Scanner/Microimager 990).
The Image Manager provides border detection for use with auto-
cropping. Auto-cropping locates the edges, in both the x and y
direction of documents and outputs the actual size of the
document that was scanned.
Reverse imaging
The host computer provides information to the scanner defining
whether the image should be stored in standard or reverse
polarity.
Default polarity is black on a white background. (white = 0)
Reverse polarity is white on a black background (white = 1).

of the SX/Y/Z command.
Simplex/duplex selection
The host computer provides information to the scanner defining
whether to scan one or both sides of the document(s). Simplex
indicates only one side (the front side) of the document(s) will be
scanned, creating a single image header and a single page
image. Duplex indicates both sides of the document(s) will be
scanned, creating two image headers and two-page images.
